Summary
Mercedes-Benz GLC-Class
Let’s make one thing clear from the very beginning - this new Mercedes-AMG GLC63 S E Performance is technically superior to the model it replaces. Whether it’s actually better or not, is the real question at the heart of the matter.
Why? Because, like the C63 sedan stablemate, AMG has opted to replace the previous model’s 4.0-litre twin-turbo V8 engine with a new 2.0-litre four-cylinder hybrid powertrain. It was a move brought about in part because of increasingly stricter emissions standards in Europe, but also ties-in with the German firm’s success in modern Formula One racing.
While the new hybrid system offers more power, more torque and better fuel economy, as the lukewarm response to the C63 has demonstrated, the hard reality for AMG is that its buyers associate it with V8 and even V12 engines. That emotional pull is hard to replace with logic, even if the new model offers technical superiority.

Audi Q5
Audi has had a mixed history with plug-in hybrids (PHEV) in Australia. Under its ‘e-tron’ banner it has launched PHEV versions of the previous A3 hatch, and the Q7 SUV, with limited success.
But the German marque believes the time is right to add plug-in power to one of its most popular models - the Q5 mid-size SUV.
With decent driving range and a packed standard features list, Audi is not messing around. But how does it stack up value wise against the already popular BMW X3 and Volvo XC60 PHEVs?

Verdict
Mercedes-Benz GLC-Class7.7/10
Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.
Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.
Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.
For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.

Audi Q57.9/10
It might be a late return to the PHEV game for Audi, but it’s an impressive one. Everything great about the Q5 remains - dynamically engaging, responsive powertrain - but you get the added benefit of electric power.
This could be the car to prove that plug-in hybrid medium SUVs don’t have to be bland family transport. If the Q5 is anything to go by, going green can be downright fun!

Design
Mercedes-Benz GLC-Class
The GLC63 is unmistakably an AMG from the moment you first lay eyes on it. That’s thanks to the AMG-specific elements, starting with the grille with vertical strikes and the AMG crest on the bonnet; which is now a signature item for the performance sub-brand.
The GLC63 is also fitted with the Night Package II design kit; this adds a darkened grille and black chrome badging to further enhance its visual appeal.
The AMG-specific alloy wheels and more aggressive stance do mean the GLC63 stands out from the rest of the GLC range, helping it look fast even when it’s standing still.
Audi Q5
The second-generation Q5 has been around for six years, and it was very much an evolution of the original, but it still looks attractive in the metal. You couldn’t call it edgy, but it is handsome.
Both PHEV body styles get the S line exterior package as standard, which adds a unique honeycomb grille, S line bumpers front and rear, Audi Sport wheels and it borrows the rear spoiler from the SQ5.
While many will favour the swoopy Sportback body style, I think the Q5 is at its most arresting in SUV body style, bathed in the gorgeous 'District Green Metallic' paint. Stunning.
Inside, only the Sportback gains the S line interior, which includes a leather three-spoke steering wheel with multifunction, shift paddles and hands-on detection, Nappa leather upholstery with contrast stitching, and aluminium inlays. The SUV seats are leather-appointed.Â
It’s fair to say Audi’s interiors have modernised since the launch of this Q5 in 2017, but it’s still hard to fault. The multimedia screen jutting out the top of the dash is a little old school these days, but the materials and quality are top notch.
Practicality
Mercedes-Benz GLC-Class
Inside the GLC63 is clearly a derivative of the rest of the range, with its C-Class-inspired design and layout, but there’s enough AMG-specific elements to ensure it looks and feels special. This starts with the AMG steering wheel, which comes not only with a thick rim wrapped in Alcantara, but also some AMG special dials to adjust the various performance settings for the powertrain, suspension and transmission.
Then there are the AMG-specific seats, which look good and offer good support for the driver and front seat passenger. The rear seats offer decent space for what is a mid-size SUV, with room enough for two adults or teenagers or three smaller kids.
Those in the back aren’t particularly well looked after though, with only rear air-con vents and small door pockets but no USB charging ports or other small item storage.
The boot is 590 litres, down from 620L in the rest of the range, thanks to the addition of the rear-mounted electric motor. There’s also no room for the temporary spare the rest of the GLC range gets and instead you have to make do with a puncture repair kit.
Audi Q5
As - predominantly - a family hauler, the Q5 has always done well in the practicality stakes. And adding a plug-in hybrid powertrain hasn’t changed that. Although you do lose some boot space compared with the petrol models - but more on that in a bit.
Up front, the Q5 has plenty of nooks and storage slots in the console, including a longer shallow slot to hold phones. The central bin is deep enough and the door bins can swallow big bottles and more. Housing the phone charger on the top of another storage spot in the console works as it can be hidden by the larger storage lid for security.
As the Q5 is older than some of Audi’s fresher models, there are physical buttons for things like air conditioning, seat heaters, and controls for drive modes and other vehicle functions.
It might not look as schmick as having a screen to house everything, but from a practicality and safety perspective, it’s welcome.
This approach also extends to the multimedia system which is fairly simple to navigate with a logical menu. Audi’s system gets a tick, as does the digital cockpit - something the brand pioneered.
While the leather appointed seats in the SUV are nice, the quilted Nappa leather seats in the Sportback are much more luxurious. And the ‘Rotor Grey’ colour scheme is simply beautiful. They offer more than enough support in the front row and they are comfy without being super plush.
There’s ample leg and headroom in the front row.
That is the same for the second row. So much headroom even with a panoramic sunroof. And behind my 183cm (six foot) driving position, there was room to spare in front of my knees. It’s such a good size.
Also, the rear seats have some bucketing so passengers will feel a little spoiled. There’s also knee-level air vents, map pockets, two USBs and a 12-volt port, a fold-down armrest with cupholders and ISOFIX points on the outboard seats.
The rear row folds 60/40 and there’s decent room in the boot, which has a power operated tailgate.Â
Â
Given some of the PHEV hardware sits directly under the boot floor, it’s little surprise that the SUV version (465 litres) loses 55L of space compared with the petrol-powered 45 TFSI.
Similarly, the Sportback (455L) drops by 45L. Also, despite the swoopy roofline, the Sportback only loses 10L of cargo space compared with the more practical looking SUV.
Those PHEV bits also mean there is no spare wheel - only a tyre repair kit.
Price and features
Mercedes-Benz GLC-Class
The power and torque figures aren’t the only numbers that have risen sharply, with the GLC63 clearly impacted by a double whammy of inflation and the usual new-car price rise.
The GLC63 now starts at more than $191,814 for the SUV and $198,415 for the Coupe, which represents a nearly $30k increase over the old V8-powered model, which was priced at $164,600 just two years ago. Even for luxury car buyers that’s a big jump, especially when you’re trying to convince people of the merits of the four-cylinder powertrain.Â
That also means it's more expensive than all of its key competitors, including the BMW X3 M Competition, Maserati’s Grecale and the outgoing, petrol-powered Porsche Macan GTS.
To help explain some of this price increase Mercedes-Benz Australia has opted for a high level of standard specification for local cars. Standard equipment includes 21-inch alloys, AMG composite braking, a panoramic sliding sunroof, a unique AMG steering wheel, power-adjustable sports seats in Nappa leather, a head-up display, dual-zone climate control, wireless smartphone charging and a Burmester 3D Sound system.
Also included is the AMG Track Pace suite, for those who want to unleash their GLC on the racetrack.
There’s also a limited run, AMG Edition 1 Package available too, for an additional $12,900. On the outside you get Manufaktur graphite grey magno paint, foiling with colour gradation and large AMG logo on the sides, an AMG Aerodynamics Package, unique alloy wheels with Edition 1 and AMG branding, yellow brake calipers and an AMG fuel filler cap in silver chrome with AMG lettering.Â
Inside there’s AMG Performance seats, AMG Nappa leather in black with yellow contrasting stitching, AMG illuminated door sills, carbon-fibre AMG trim highlights, yellow seat belts and a unique AMG Performance steering wheel wrapped in carbon-fibre and microfibre.
Audi Q5
Dipping its toe back in the plug-in hybrid market, Audi is keen to appeal to buyers looking to reduce their carbon footprint, but also to driving enthusiasts requiring a bit of zing with their environmental credentials.
That’s where the Q5 55 TFSI e quattro comes in. Audi Australia had the option of introducing a less performance focused Q5 PHEV grade, but opted instead for the higher output model.
Audi sees this as the SQ5 you buy when you want to save the planet. And the 0-100km/h sprint time of 5.3 seconds suggests it’s pretty close.
Pricing for the 55 TFSI e quattro starts at $102,900, before on-road costs, for the SUV body style.
Opting for the Sportback carries a $7300 premium, making the price $110,200. But you get some more gear in the Sportback over the SUV, including the S-line interior package, and Matrix LED headlights with dynamic front and rear indicators.
Other equipment standard on both grades includes a panoramic sunroof, hands-free power tailgate, ambient lighting (with 30 colours), keyless entry and start, front leather-appointed seats with heating and power adjustment, three-zone climate control, a 10.1-inch multimedia touchscreen with wireless Apple CarPlay and Android Auto, digital radio, 10-speaker audio, auto-dimming interior mirror and 20-inch Audi Sport alloy wheels.
You can opt for different 20-inch wheels or 21-inch hoops as well.
The 'Technik' option pack costs $4900 for the SUV and $4700 for the Sportback and adds a head-up display, a more premium Bang & Olufsen audio system, and high-tech head or tail-lights, depending on the body style.
All in all it’s a healthy standard features list. I’ve said it before recently, but it’s worth repeating - it’s good to see premium brands including more standard features in their models, rather than making everything an option.
That said, maybe heated rear seats (as well as the standard front seats) might have been a nice addition.Â
So, how does the Q5 compare with its PHEV counterparts? Its most obvious rival is the BMW X3 xDrive30e which is more expensive at $111,800.
Then there’s the Range Rover Evoque R Dynamic HSE ($104,310) and Volvo XC60 Recharge ($101,990), which line up closely with the Audi, while the Lexus NX450h+ undercuts them all ($91,423).
Under the bonnet
Mercedes-Benz GLC-Class
This is what lies at the heart of the AMG GLC63’s success or failure. As I mentioned at the beginning, the previous generation’s 4.0-litre twin-turbo V8 has been replaced by an F1-inspired plug-in hybrid powertrain.
But don’t think that means AMG is suddenly focused on efficiency over performance. When AMG says the powertrain is inspired by the brand’s success in Formula 1 racing, what it means is the battery and electric motor provides a significant performance boost to support the internal combustion engine, not just save fuel.
To that end the combination of the turbocharged 2.0-litre four-cylinder petrol engine and the rear-mounted electric motor produces an impressive 500kW and 1020Nm. That’s a massive jump over the 375kW/700Nm made by the outgoing V8.
Audi Q5
The Q5 pairs a 2.0-litre four-cylinder turbo-petrol engine - found in many VW Group products - with a plug-in hybrid set-up that includes a lithium-ion battery pack and an electric motor.
The total system output is 270kW of power and 500Nm of torque, which is impressive. In fact, it has more power - but a little less torque - than the SQ5 performance flagship.Â
It drives all four wheels thanks to Audi’s quattro all-wheel drive system, and does that via a seven-speed dual-clutch automatic.
Efficiency
Mercedes-Benz GLC-Class
Mercedes makes no secret that the battery is designed for performance, not saving fuel. It only has a 14km EV range but can recharge quickly on the move to provide a power boost when needed.
But despite all that, the GLC63 is actually significantly more fuel efficient than the old V8, using a claimed 7.3L/100km, which is a massive 4.9L/100km improvement over the old model. Although, on our day-long test drive we didn’t manage to come close to that claimed figure and instead saw returns around 11L/100km, albeit after a lot of spirited open-road driving.
Audi Q5
The PHEV’s battery capacity is 17.9kWh and that ensures the Q5 has an electric driving range of up to 55 kilometres on the WLTP protocol.Â
Audi says the average daily commute of an Australian is 35km, so technically many people could get to work and back using electric power only.
It might not sound like a huge amount, but it’s more than the 41km offered by the BMW X3, although it doesn’t come near the Lexus NX’s 87km claim.
Energy consumption is rated at 23.9kWh/100km, and the official fuel consumption figure for the Q5 is 2.0 litres per 100km - bettering the X3’s 3.2L/100km figure but not as frugal as the Lexus (1.3L).
It has a 54-litre fuel tank and emits 45 grams per kilometre of CO2.
The Q5 PHEV has a Type 2 plug and comes with a charger to add more juice at home.
It has an AC charging capacity of 7.2kW and it will take two and a half hours to fully charge using a home wallbox charger. You can also plug it into a regular wall socket at home and it’ll be charged up in about eight hours, or overnight. It's not capable of DC charging.
Driving
Mercedes-Benz GLC-Class
Anyone who still believes in the adage ‘there’s no replacement for displacement’ hasn’t driven a modern turbocharged and hybridised engine. The GLC63 is a demonstration of the metaphorical and literal power of modern technology, combining an extremely efficient and potent internal combustion engine with an electric motor to make enormous real-world performance.
To be blunt, the GLC63 feels like a rocketship out of corners, launching with a ferocity and relentlessness the old V8 simply can’t match. It shouldn’t come as a surprise, a mid-size SUV with 1020Nm was always going to have plenty of performance, but even so it’s a shock to the system every time you give the GLC63 full throttle. Officially AMG claims it takes just 3.5 seconds to run 0-100km/h and has an electronically limited top speed of 275km/h - mighty impressive figures for a five-seat mid-size SUV.
To help get all that torque to the road, AMG deploys torque distribution technology that allows for it to be split an even 50/50 front/rear all the way to 100 per cent to the rear tyres.
Other technologies deployed to enhance its handling include AMG Ride Control suspension with adaptive damping and rear-axle steering. There’s also eight AMG Dynamic Select driving modes and four AMG Dynamics settings (Basic, Advanced, Pro and Master), so it’s a complex vehicle that is designed for the enthusiast.
While it’s easy to drive around town, once you get out on the open road you can really get a sense of the GLC63’s performance potential. Beyond just its powertrain the suspension offers good body control and the rear-axle steering helps it feel agile and responsive.Â
It’s not perfect though. At times the complexity of the system does lead to some hesitation when you put your foot down. It certainly lacks the linear power delivery of the old V8 and makes for a slightly trickier driving experience at times.
As for the sound, which is one of the biggest elements missing from the V8, Mercedes has added AMG Real Performance Sound, which features a pressure sensor in the exhaust that picks up on the engine note and plays it through the speaker system. It certainly helps make for a louder, more noticeable engine noise, but it still sounds more like an A45 than the previous GLC63 and for many would-be buyers, that’s a major turn-off.
Audi Q5
The Q5 has always been the driver’s pick among its peers - specifically the BMW X3 and Mercedes-Benz GLC. You could argue a Porsche Macan is more engaging and you’d probably be right. But of those immediate German rivals, the Q5 takes the cake.
Adding a PHEV powertrain and the circa-300kg of extra weight that brings should impact dynamics - but somehow, it doesn’t.Â
First of all, the Q5 PHEV can do the 0-100km/h dash in just 5.3 seconds which is hot hatch territory.Â
But the really impressive thing about this Q5 is how well it handles, despite that extra weight. The battery pack is housed under the boot floor, and Audi engineers have done a bang up job in ensuring it retains that dynamic prowess it's known for.Â
We drove on some delightfully twisty roads in the Gold Coast hinterland for this launch event, and the Q5 didn’t miss a beat.
It maintained composure when pushed into tight corners, and had plenty of grip. And the electric urge coming out of those corners - providing you have battery charge left - only helps the experience.
Typically sharp Audi steering is indeed present and welcome.
Riding on 20-inch Audi Sport alloy wheels, and with a sporty bent, you’d think the ride quality would be impacted. But that was another pleasant surprise.
The Q5 soaks up corrugations with the standard suspension set-up, and the tyres have a decent sidewall. So no unpleasant sharp bumps detected.
The cabin is reasonably well insulated from most outside intrusion as well.
Safety
Mercedes-Benz GLC-Class
The GLC63 comes standard with a comprehensive suite of safety features including 'Distronic' (Mercedes’ name for adaptive cruise control), 'Active Lane Keeping Assist', 'Blind Spot Assist', 'Traffic Light Assist' and 'Adaptive Highbeam Assist'. It also includes Mercedes’ 'Pre-Safe' accident anticipation system - which pre-tensions the seat belts and will even play a white noise to protect your ears if it senses a crash is imminent.
A parking system that includes a 360-degree camera and active parking assist is also included.
The GLC range was awarded a five-star ANCAP rating in 2022, which pre-dates the latest testing protocols, so doesn’t provide a like-to-like comparison for vehicles tested after that date.
Audi Q5
The Q5 plug-in counts an impressive level of safety gear, including eight airbags in total, although that does not include a front centre airbag.
It comes with the usual suite of driver aids, including Audi’s ‘pre-sense city’ system that activates emergency braking at speeds up to 85km/h, ‘pre-sense front’ emergency braking up to the Q5’s maximum speed, as well as attention assist, an active bonnet, a tyre pressure monitor, and hill descent control.Â
It also features adaptive cruise control, lane keep assist, blind spot monitor, safe exit assist, cross traffic alert and a 360-degree camera with an excellent display.Â
While the rest of the Q5 range is covered by a five-star ANCAP safety rating dating back to 2017, the Q5 plug-in hybrid remains unrated for now.
Ownership
Mercedes-Benz GLC-Class
The GLC63 is covered by Mercedes Australia’s usual five-year/unlimited kilometres warranty.
As for maintenance, Mercedes offers service plans, spanning three to five years. Three years will cost you $5025, $6455 for four years and five years is priced from $7180. Servicing intervals are 12 months or 20,000km, whichever comes first.
Audi Q5
The Q5 comes with Audi’s five-year/unlimited kilometre warranty. This was an increase on its previous term that Audi announced at the start of 2022. The PHEV is also covered by an eight-year/160,00km battery warranty.
Service intervals are every 12 months or 15,000km, whichever comes first, and Audi offers a capped-price service plan for five years that costs about $3500 all up. That’s a little pricer than BMW and Volvo’s plan.
